The rotor’s overall diameter of 250 mm and nominal thickness of 22 mm ensure compatibility with factory specifications, maintaining proper braking performance and safety. The smooth surface type provides consistent friction against brake pads, reducing uneven wear and noise. With four mounting bolt holes arranged on a 103 mm bolt circle diameter, installation aligns precisely behind the hub, matching OEM fitment requirements. The discard thickness of 20 mm serves as a critical indicator for rotor replacement to maintain optimal braking efficiency.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement for worn or warped rotors on Nissan 300ZX\u003c\/li\u003e\n\u003cli\u003eAddresses brake fade caused by overheating through vented design\u003c\/li\u003e\n\u003cli\u003eEliminates vibration and noise from uneven rotor surfaces\u003c\/li\u003e\n\u003cli\u003eRestores proper rotor thickness for safe braking performance\u003c\/li\u003e\n\u003cli\u003eCompatible with vehicles lacking ABS tone ring requirements\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEnsure rotor mounting surface is clean and free of debris before installation\u003c\/li\u003e\n\u003cli\u003eTorque mounting bolts to manufacturer specifications for secure fitment\u003c\/li\u003e\n\u003cli\u003eCheck brake pads for wear and replace if necessary during rotor installation\u003c\/li\u003e\n\u003cli\u003eVerify rotor thickness is above discard thickness before installation\u003c\/li\u003e\n\u003cli\u003eUse proper tools to avoid damage to rotor surface and mounting holes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eCentric’s C-TEK Standard Disc Brake Rotors are manufactured to meet or exceed OEM standards, providing reliable braking performance and durability.
